Superior VDI Experience – Flash Array & Citrix XenDesktop


Delivering a superior VDI experience with Flash Array and Citrix XenDesktop

VDI – Virtual Desktop infrastructure is the practice of hosting a desktop operating system within a virtual machine (VM) running on a centralized server. VDI is a variation on the client/server computing model, sometimes referred to as server-based computing. VDI has become more popular, now available to most workers, anyplace, anytime, via multiple devices.

Virtualizing and centralizing desktops offers a more secure, more manageable and less costly end-user computing model. Scalable server architecture has helped with this, although virtualizing and centralizing are more popular now they are still not widespread.

The reason being high cost and management complexities. VDI deployment should reduce equipment costs and management costs although the initial shared server and networking resources can have an expensive price tag. VDI that relies on spinning disk storage systems tend to deliver unreliable performance and slow response times. VDI projects are usually deployed with the goal of maximizing end-user productivity, which is great, but usually this means increased IT management.

When considering a VDI storage solution it is important to value high performance with consistent low latency as well as non-disruptive operations. Low latency storage compatibilities are required to enable the full potential of VDI designs. Otherwise the systems will get bogged down and users will experience inconsistent performance and disconnections when multiple devices log in at the same time. The system must be available at all times even during maintenance, upgrades, natural disasters etc. Storage systems that cannot perform consistently will not be able to support VDI installation.

Pure Storage Flash Array and Citrix XenDesktop in perfect harmony

The Pure Storage Flash Array delivers low latency performance with the average latency being less than 1 millisecond. Flash Array’s typical data reduction rate of 10:1 or greater cuts costs than with traditional disks and hybrid storage. The average up time for Flash Array storage systems is greater than 99.999 percent – extremely reliable. Flash Array also employs a set and forget system that simplifies VDI management. In addition this storage solution has non-disruptive operations that give that same reliable performance even during upgrades and maintenance.

Citrix XenDesktop delivers full Windows VDI capabilities in addition to virtual apps, meeting the demands of any user. XenDesktop enables users to access their apps, desktops and data without the limitations of a traditional solution. On the unified FlexCast Management Architecture (FMA) platform, XenDesktop is the only solution that is FIPS-compliant and Common Criteria certified to meet the highest security standards of regulated industries. End users will enjoy the simple virtual desktop interface, while IT will appreciate the superior performance of HDX technology, even when deployed over challenging, high-latency networks.
